MARINE WEATHER DISCUSSION FOR N ATLANTIC OCEAN
NWS OCEAN PREDICTION CENTER WASHINGTON DC
324 PM EDT SAT MAY 30 2015

.FORECAST DISCUSSION: MAJOR FEATURES/WINDS/SEAS/SIGNIFICANT
.WEATHER FOR THE NORTH ATLANTIC OCEAN W OF 50W FROM 30N TO 50N.

LATEST SAT PIX SHOWS MAINLY PARTLY CLOUDY CONDITIONS ACROSS MUCH
OF THE OFFSHORE WAATERS WITH ERLY WINDS ACROSS MUCH OF THE NT2
WATERS VEERING TO SRLY OVR FAR NRN NT1 WATERS. AN ALTIMETER PASS
FROM 14Z SHOWS SEAS GENERALLY 3-6 FT ACROSS MUCH OF THE REGION
WITH MAX CONDITIONS TO 7 FT. ASCAT PASS FROM 14Z THIS MORNING
INDICATES A NE-SW RIDGE AXIS STRETCHING FROM N OF GEORGES BANK TO
THE MID-ATLANTIC CST...WINDS OVR THE WATERS ARE VARIABLE 5-15 KT
ATTM.

THE 12Z GLOBAL MODELS ARE IN VERY GOOD AGREEMENT THROUGH THE
RMAINDER OF THE WEEKEND..THEN BEGIN TO STRAY JUST A BIT DURING
THE DAY MON...MAINLY DEALING THE POSITION OF THE BACK DOOR COLD
FRONT AS IT SAGS S OFF THE NEW ENGLAND CST. THE GFS BRINGS THE
FRONT THE FURTHEST S AMONG THE GLOBAL MODELS. A WEAK WAVE IS FCST
TO FORM ALONG THE FRONTAL BNDRY AND MOVE NE OVR NT1 WATERS. I FEEL
FAIRLY CONFIDENT POPULATING THE WIND GRIDS USING THE GFS 10M
THROUGH 00Z THURSDAY...THEN TRANSITION TOWARD THE 12Z ECMWF FOR
THE REMAINDER OF THE PERIOD. THE 12Z GFS LATER IN THE WEEK TRIES
TO FORM AN INVERTED TROF ALONG THE SE COAST...WITH ENHANCED WINDS.
THIS FEATURE IS NOT INIDICATED BY THE OTHER GLOBAL MODELS AND IS
AN OUTLER IN THIS SCENERIO.

.SEAS...SIMILAR TO THE WIND GRIDS WL USE 12Z WNA INTO 00Z THU
BEFORE TANSITIONING WVHTS TO 12Z ECMWF WAM.

.EXTRATROPICAL STORM SURGE GUIDANCE...N/A.

.WARNINGS...PRELIMINARY.

.NT1 NEW ENGLAND WATERS...
     NONE.

.NT2 MID ATLC WATERS...
     NONE.
